The Bosch Rexroth SEM-E-S 20X5LX3-4 (R155211014) is an adjustable preload single nut designed for precision ball screw assemblies. This SEMES series nut has a nominal diameter of 20 mm and a lead of 5 mm with a left-hand thread direction, ensuring compatibility with specific application requirements. It features a standard seal and standard axial clearance, optimized for maintaining performance while minimizing friction. The SEM-E-S 20X5LX3-4 is crafted to accommodate dynamic load capacities specific to tolerance grades T3 and T7, as detailed in the Bosch Rexroth General Technical Notes and Information. Users are advised to refer to the correction factor f_a for other tolerance grades to ensure accurate load capacity calculations. The static load rating, as well as additional technical parameters, are aligned with these same tolerance grades. This ball screw assembly nut operates efficiently within a temperature range of -10°C to +80°C, allowing for continuous use at temperatures up to 80°C and withstanding temporary peaks up to 100°C. These temperature measurements are taken on the outer shell of the nut, assuring reliable operation under various thermal conditions. Bosch Rexroth's SEM-E-S 20X5LX3-4 also comes with an impressive maximum permissible linear speed (v_max), although users should consult the Characteristic speed (d_n) and Critical speed (n_cr) sections in the Technical notes for optimal usage parameters. This product's design includes several ball track turns and features a hole pattern designated as BB. The SEM-E-S 20X5LX3-4 is built for zero-clearance adjustability within its class, providing precise control over axial movement in demanding applications. Its weight is calibrated according to its nominal size specifications, ensuring that it integrates seamlessly into existing systems without requiring extensive modifications. With its robust construction and precise engineering, this Bosch Rexroth ball screw nut is an essential component for sophisticated linear motion tasks requiring high accuracy and reliability.
